What do you play?
When I was in high school, I was in five(!) different rock bands. Only me and one other guy were the only ones who went through all five.
I played bass, but would occasionally play drums, too.
The cool thing was, all five bands played pretty much the same stuff: covers of rock songs from the 1960s and 1970s. So it was easy to adapt. Although one band I was in, the Rovers, were a bit more ambitious. They wrote a lot of their own stuff. I tossed in a few lyrics here and there, but our lead singer considered himself the chief lyricist/leader of the group.
Unfortunately, I sold my drum set the summer before I started college. I wish I still had it. The kid I sold it to eventually sold it to someone else, so now I have no idea where it is.
I still fool around on the bass once in a while.
